To establish updated population-based reference intervals for serum magnesium levels in children and adults in the U.S.
Utilized data from nonpregnant, nonlactating participants in the 2021–2023 NHANES cycles.
Applied linear regression models to compare serum magnesium levels across subgroups.
Categorized children by sex and adults by sex, age, and metabolic health status.
Mean serum magnesium levels were lower for girls than boys (p=0.003) and decreased in adults with diabetes, hypertension, and chronic kidney disease (p<0.001).
Reference interval for boys was 1.70–2.19 mg/dL and for girls was 1.64–2.18 mg/dL.
67.8% of adults showed signs of chronic latent magnesium deficiency (serum <2.06 mg/dL).
